Are those LEDs 1watt? Why is a + lead put into the water at bottom? Shouldn't the water have ground negative that connects with the other leads to complete negative connection to the LEDs?
hello, first of all, you can use any led. I just used these carcasses because they are easy to work with. The other issue is that the uln2003 IC works the same as the bc547 logic. negative is directly connected, if positive, it is placed at the bottom
Merhaba Mehmet bey
Devreyi monte edeceğim yer ile depo arası 35 metre devrenin çalışmasında sorun olurmu?
Saygılar
Merhaba erkan bey normalde sorun olmaması lazım ama devre çalışmasa yada zor algılarsa kablo kesitini biraz daha artırman gerekecek kolay gelsin
